The 1010 concept Hybrid Automated Manual gearbox has been developed for premium Sportscar applications. Developed under the “Race to Road” banner, the design draws on Xtrac’s peerless pedigree in Le Mans and Sportscar racing to deliver a CO2 emission beating road car transmission.

Xtrac’s precision design and manufacturing engineering capabilities have ensured that the ground helical gear sets will deliver market leading NVH refinement for the most demanding EV modes.

Particularly suited to mid-engine or front mid-engine sports cars, the transmission features an overlapping ratio gear shift system to improve shift times. With the addition of hybridisation, the shifts are further improved by the ability to “Torque Infill” up to customer defined maximum speeds (Circa 150km/h). Hybridisation also provides a pure EV mode along with a KERS style boost at higher speeds for overtaking.
